Update Certbot to use the latest Validation Method (ACME EOL!)

If you are using Cerbot and also have received an E-Mail from Let’s Encrypt, informing you that the ACME-TLS-SNI-01 Domain Validation reaches End of Life on February 13. 2019, I have an easy way for you to Update Cerbot to use the latest Validation Method.

TLS-SNI-01 validation is reaching end-of-life and will stop working on **February 13th, 2019.**

You need to update your ACME client to use an alternative validation method (HTTP-01, DNS-01 or TLS-ALPN-01) before this date or your certificate renewals will break and existing certificates will start to expire.

If you need help updating your ACME client, please open a new topic in the Help category of the Let’s Encrypt community forum:
